You are off the coast of Mexico and are taking a time tick for 1800. At approximately 1754, you hear the preparatory signal "VVVV de XDD" from the time signal station. Then you hear a series of 1 second dashes followed by a 9 second silent period and then a long 1.3 second dash. At the beginning of the long dash, your comparing watch reads 06h 00m 07s. When compared to the chronometer, the comparing watch reads 06h 01m 24s, and the chronometer reads 05h 59m 23s. What is the chronometer error?

Correct Answer: Option C — 1m 54s slow
Chronometer error is the difference between the chronometer time and the correct time signal. The watch reads 06:00:07 at the signal, while the chronometer reads 05:59:23, indicating the chronometer is 44 seconds slow relative to the watch. Given the watch is 1 minute 10 seconds slow relative to the chronometer, the total error is 1m 54s slow.
